ABC News - Mother whale caught in apparent act of mourning for dead calf
The transcript discusses the emotional behavior of a mother orca, known as J35, who is seen carrying her deceased calf in an apparent act of mourning. This behavior has been observed before, as J35 carried another calf's remains for over 1,000 miles over 17 days seven years ago. The high calf mortality rate among orcas is concerning, with only 50% of newborns surviving their first year. Southern resident killer whales, like J35, face threats from food scarcity, pollution, and vessel noise, putting them at risk of extinction. Despite these challenges, there is hope as researchers have observed a new calf in the pod that appears healthy. Additionally, orcas have been exhibiting unusual behaviors, such as attacking ships in Europe, which researchers attribute to playful behavior by younger whales. Researchers plan to continue monitoring J35's pod for a few more weeks before they migrate from Seattle.
Key Points:
- Mother orca J35 seen mourning deceased calf, highlighting emotional capacity.
- J35 previously carried another calf's remains for 1,000 miles over 17 days.
- High calf mortality among orcas; only 50% survive their first year.
- Southern resident killer whales face extinction threats from food scarcity, pollution, and noise.
- New calf observed in J35's pod offers hope; researchers will monitor pod before migration.
